Replacing the microprocessor
Attention
Do not open your computer or attempt any repair before reading the “Important safety
information” in the Quick Reference that was included with your computer or in the
Hardware Maintenance Manual (HMM) for the computer. To obtain copies of the Quick
Reference or HMM , go to http://www.ibm.com/pc/support/.
When you receive a new microprocessor, you will also receive a new heat sink and
vacuum pen. You must use the new heat sink with the new microprocessor. If you
use the old heat sink with the new microprocessor, your computer might over heat
and could cause intermittent problems.
Important
Do not touch the gold contacts on the bottom of the microprocessor. Use the
vacuum pen provided to remove and install the microprocessor. If you must
touch the microprocessor, touch only the sides.
This section provides instructions on how to replace the microprocessor.
Important
Leave your computer turned off for at least one hour before removing the
microprocessor to allow the thermal interface between the microprocessor and
the heat sink time to cool down.
1. Open the computer cover. See “Opening the cover” on page 5.
2. Pivot the drive bay assembly upward to gain access to the system board.
3. Locate the microprocessor fan connector on the system board. See “Identifying
parts on the system board” on page 4.
4. Disconnect the microprocessor fan cable from the system board.
